What causes a 2000 Chevy Blazer not to start?

175

Asked by Aug 02, 2012 at 10:13 AM about the 2000 Chevrolet Blazer 4 Door LT

Question type: Maintenance & Repair

When the key is turned there is no sounds at all. All interior electric and the running headlights come on. I have replaced the alternator, battery, relays, starter, and nothing. What am I missing that can be the problem. One other thing is when the power does reach the starter the starter acts as if it is a bad starter by spinning, but not engaging. It did this once. I had the starter tested and it worked.

Do you hear the fuel pump prime when you turn the key to on? If not, then your not getting fuel and the care will just crank but not start.

The fuel pump is priming, but nothing is cranking. I have a engine with nothing making any noises. Turn key and just no noise from starter, or anything outside of a few electrical items. Now wondering about ECU going out.

The ecm won't prevent the starter from turning or engaging try jumping the starter with the key on. Little stud to big stud, if it turns over then check ur ignition switch.

Btw if it turns over with the key on then it should start. If it doesn't turn over then check voltage at the big stud. Its marked B
